It was April 16 of 2013, almost exactly four years ago, when emergency manager Ed Kurtz signed the contract that switched the city of Flint to the Karegnondi Water Authority (KWA). It was heralded as a cost-cutting move.

That decision led to one of the biggest water contamination crises in American history.

The lead poisoning forced the city to go back to getting its water from the Great Lakes Water Authority, which serves Detroit, until the KWA system was in place.

Choosing a new superintendent is the first major task for Detroit’s newly-elected school board, which just took power in January after years of state control. But the process has already become messy and controversial.

Macomb County Clerk Karen Spranger has been a source of controversy since her election last fall. Now two of Spranger's former deputies are suing their old boss.

The lawsuit, filed in U.S. District Court Friday, says that Paul Kardasz and Erin Stahl were fired in retaliation for submitting ethics complaints against Spranger. The pair is being represented by attorney Jennifer Lord.
